Thank you Snick as I have explain using monitor i have detected that is nsurlesssessiond and cccloud the take more than 192 % of the processor work when photos is active and use all the disponible upload to update photos library to ICloud abd com.apple .photos. videoconversion.service. I upgrade my I cloud account to have more capacity yesterday to see if the probleme is related to the metadata and storage capacity of my account, but nothing really changes it stills more than 18000 photos to update ...
the VTEncoderXPC or DECODER service takes sometimes more than 393% processor capacity!!!!
I try many times but actually in france it's seems that apple support has problems to contact their clients, by exemple Apple support sent you a message saying that they are calling you to your phone number and they fall in our message box but it's false.
